Hello, I'm looking to buy a waterblock for a 6800 ultra. Probably the bfg oc. However, I was wondering that if I remove the fan from the card and replace it with a chip waterblock, what about the ram. Wont they burn to hell with out cooling. Or can they run just fine with no cooling. I've only found the dander den waterblock that cools the memory too, but it's so freaking expensive at 130 dollars. Is there anywhere that has the danger den cheaper. I was looking at the koolance waterblock, they have it for 40 dollars but the ram has no cooling. That is what worries me.

The memory will likely be fine but you just may not have as much overclocking headroom on them. You could put passive ram sinks on the memory modules.

Unless you volt mod your ram it won't 'burn' even if you do overclock it a bit. Like Clay said you just won't be able to overclock it as much. Which block are to thinking of getting? Are you also going to watercool your CPU too?

Yeah, I've already bought everything in my system. I have a koolance case with pump and a koolance 300 waterblock for my amd 3800+. I was just looking at the thermaltake memory cooling kit, and they seem to have a pretty good passive cooling ramsink. Do you think these would work on a 6800 ultra? How bout size? Will these fit any 6800?

This one then?

Cool-Matic NV40 (http://www.webshop-innovatek.de/00000094271139704/000000942713b3501/50142494350d3d711/500988952d0c00102.html)

Don't know if it will work in your system...

In my opinion RAM sinks aren't really worth it unless you have massive amounts of air blowing on them. Which Koolance case did you get?

Well ramsinks do work.. after pputting them on my 9800 pro I was able to OC the memory a little more. If you think about it, all its doing is redirecting the heat away from the chip, on to the fins. It is pointless without a fan blowing on it, but even a little bit of airflow will help.

This is what i have done to a GT. (pic's) (http://www.nvnews.net/vbulletin/showpost.php?p=393575&postcount=9) If you do a d.i.y. gpu water cooler using a cpu water block you can actually keep the GT's ram cooler section on the board (if its a reference design fan) it is actually seperate from the fan/heatsink/cover section. Not 100% sure for Ultra tho.

I'm running my CPU & GPU cooled by a Koolance PC2-650 case.

GPU, under full load and OC'd to 470, never goes past 62c.

I'm using the GPU-180-L06 from Koolance. Got it for something like $40.

Works like a champ!

Thats what I did with mine, Works AWESOME!!!! Be fore warned though, I called BFG and taking off your fan voids the lifetime warranty.

I have the koolance 650. IT's an awesome case. I have yet to finish building the system but i read nothing but great reviews on this case. However, my case doesnt have any fans on it(other than the radiator ones). I dont want to put any fans, because what i'm looking for is silence. That is why I bought this case. I had an fx-53 system with a good thermaltake volcano and even though it was relatively quiet, it was still anoying to my sensitive ears. However, what i want to know, is, will my memory chips(NOT overclocked) in my gf6 ultra be OK, or do I have to put sinks on them. I'm just thinking of leaving the sinks that come with the card. Didnt know they were seperate than the fan. Thanks Black Sun!

i also have the pc2-650 case and like it alot. i'm using the GPU-180 on my 6800gt along with a vantec spectrum fan. i put iceberq copper ram sinks on the card. the card is running @ 406/1.08. idle temps are 47-48 and under load goes into the mid 50's.
